Patented Feb. 17, 1931 UNITED STATES PATENT OFFICE CLARENCE 1. CHAMBERLIN, OF DETROIT, MICHIGAN, ASSIGNOR T METAL MOULD- INGS CORPORATION, OF DETROIT, MICHIGAN, A. CORPORATION OF MICHIGAN HINGED SASI-I AND FRAME Application filed June 7, 1929. Serial No. 369,036.

tending into the channel and forming a weather tight connection.

Another object of the invention is to provide a sash which is pivoted in the frame and the frame is provided with flanges overlapping the sash on opposite sides when the sash is closed and extending into the channels provided therefor in opposite sides of the sash.

A further object of the invention is to provide a hinged sash and frame of sheet metal construction which is weather tight when the sash is closed.

These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawings in which- Fig. 1 is an elevation of a sash and frame embodying my invention.

Fig. 2 is an elevation of the opposite side of the sash and frame.

Fig. 3 is an enlarged section taken on lme 3--3 of Fig.1.

Fig. 4 is an enlarged section taken on line H of Fig. 1.

The frame is formed of sheet metal and as shown in Figs. 3 and 4 is formed to providea channel 1 in the outer edge. This frame is also formed with a flange 2 which extends around half of the frame on one side and around the opposite half of the frame on the other side. As shown in Fig. 3 this flange terminates at 3 on one side and at 4 on the opposite side. The sash is also formed of sheet metal and is provided wlth a channel 5 in the inner edge in which the glass panel 6 is mounted and this sash is also formed to provide channels 7 and 8 in the opposlte sides thereof. The flange 2 is provided with a return bent edge 9 which extends over the op posite edge 10 of the frame and this return bent edge 9 engages in the channel 7 of the sash on one side and on the opposite side engagesin the channel 8 of the sash. This provides a weather tight closure between the sash and frame when the sash is closed. As shown in Figs. 1 and 3, the sash is provided with lugs 11 which extend outwardly and engage over the ends 4 of one of the flanges 2 to provide a pivot for the sash. At the top, as shown in Fig. 1, a spring catch 12 is provided on the sash adaptedto engage in a member 13 on the frame to hold the sash in locked position, the spring catch 12 being adapted to be manually released to allow the sash to turn to the open position. As will be seen from Fig. 3, the sash pivots on the terminal ends 4: of the flange 2 and the ends 3 provide a stop for the sash preventing it from turning beyond the horizontal position. The frame 1 is adapted to be fitted into the glass in the upper sash of the usual window and the hinged sash, shown in the drawing, may be opened tov provide ventilation in a room. This is particularly useful in ground floor sleeping rooms as the sash is too small to allow entry of a person into the room.

From the foregoing description it becomes evident that the device isvery simple and efficient in operation; will not easily get out of order;,will provide a weather-tight sash and frame and provides a device which accomplishes the objects described.

Having thus fully described my invention, its utility, and mode of operation, what I claim and desire to secure by Letters Patent of the United States is 1. In a device of the character described, a frame formed of sheet metal and having a peripheral U shaped channel open in its outer edge, a flange on the upper side of the frame extending inwardly around one half of the frame and a flan e on the opposite side of the frame extending inwardly about the lower half of the frame, the inner edge of each flange being inturned, a sash formed of sheet metal pivotally mounted on the ends of one flan e to swing on a horizontal axis and having a channel for a glass panel in its inner edge and a channel formed in each side thereof, the arrangement being such that as the sash is swung to the closed position the inturned edge of each flange engages in the respective channel formed in the side of the sash.

2. In a device of the character described, afrarne formed of sheet metal and having a flan e on one side extending inwardly about the upper half of the frame and a flange on the opposite side extending inwardly about the lower half of the frame, the inner edge of each flange being inturned, a sash pivotally mounted in the frame on the ends of one flange to swing on a horizontal axis and having a channel in each side, the arrangement being such that as the sash is swung to the closed position the inturned edge of each flange engages in the respective channel of the sash.

3. In a device of the character described, a frame formed of sheet metal and having a peripheral U shaped glass receiving channel open in its outer eoge, a flange on one side of the frame extending across the upper cross member and approximately half the length of the two side rails, and a flange on the opposite side extending across the lower cross member and approximately the lower half of the side rails, a sash formed of sheet metal and pivotallv mounted to swing on a horizontal axis, said pivotal mounting consisting of a lug on each side rail on one side thereof having the lower end extending outwardly at an angle to lie over the respective ends of the lower flange on the side rails, said sash having a channel in its inner edge to receive a glass and the side faces of the sash being formed to correspond with the inner faces of the flanges to provide a Weather tight seating of the sash in the frame when closed.

In testimony whereof I sign this specification.
